Each render is the mesh built by the object’s Sand3D program.
We created Sand3Dan LLM-friendlylanguage that writes3D objects as code
Sand3D
One program per object. A Python file that gives each part
its shape, holes, position and material.
CAD parts
Mechanical parts, in the same language. Every dimension is a parameter of the program.
Meshes
The mesh beside each program. Ready for Blender, three.js and any glTF engine.
Quality code,easy to build on
Programs a person can read and an LLM can learn from, written part by part.
Clean andcompact code
One function per part, every dimension a named parameter.
Less code,fewer tokens
Each program is optimized: fewer tokens for an LLM to read.
Programshierarchy
Each part is a function, called by the object it belongs to.
Fully open-sourced library
Programs on Hugging Face, the library on GitHub, all open.
Every objectcomes with its program
Every part has its name in the code. Change a value, run the program again, and the object follows.

Recreated in codefrom five open collections
Every object began in an open collection. Our models rewrote each one as a Sand3D program, checked against its original. The result is a 3D model fully controllable through code.
67K
ObjaverseEveryday objects, rewritten as code.
24K
CADMechanical parts, in the same language.
9.2K
ArticraftDoors and drawers, with joints in code.
2.3K
NVIDIA SimReadySimulation objects, translated to Sand3D.
3.1K
AutoMateAssemblies, mating joints included.
Articulated objectsyou can move
10K+ articulated objects and 36K joints, each checked against its source.
Every joint is declared in the program, with its axis and its limits.
